What is a catalytic converter diagram?

A catalytic converter diagram is a clear schematic that maps the internal structure and flow path of the catalytic converter. It highlights the substrate, washcoat, and catalyst materials (such as platinum, palladium, and rhodium), along with the path exhaust gases take from the engine through the converter to the tailpipe. By illustrating these components and flows, technicians can quickly identify potential failure points, plan installations, and communicate complex information to customers in an accessible way.

Why a catalytic converter diagram matters

Diagnostics: A diagram provides a visual reference that aids interpretation of diagnostic trouble codes, sensor data, and symptoms like reduced power or elevated emissions.
Installations: It guides proper orientation, mounting, and connections of heat shields and oxygen sensors to ensure optimal performance.
Maintenance: Regular inspection of the converter and adjacent exhaust components helps prevent costly failures and helps maintain compliance with emission regulations.
Customer understanding: A well-placed diagram supports clearer explanations of repairs, replacements, and the value of quality Catman products.

How a catalytic converter works: the role of the diagram

Most modern vehicles use a three-way catalytic converter to target hydrocarbons (HC), carbon monoxide (CO), and nitrogen oxides (NOx). The diagram emphasizes key stages:

Incoming exhaust: Unburned fuel and gases enter the converter and encounter the catalytic materials.
Reduction and oxidation: The catalysts drive chemical reactions that transform pollutants into less harmful substances.
Clean exhaust: Treated gases exit toward the exhaust system, reducing overall emissions.

The schematic also shows how sensors and the engine control unit (ECU) interact with the converter to optimize performance and emissions. diesel particulate filters overview.
